RFID hardware projects for RFID Security Analysis

22C3 Presentation (2005-12-27)

The presentation covers an introduction into the two popular RFID Standards, ISO14443 and ISO15693, as well as Harald's Free Software implementation "librfid" The number of deployments of RFID based solutions is growing every day. Still, detailed low-level knowledge of the involved protocols is rare, even within the hacker community. Harald's part of this presentation describes the two commonly-deployed ISO standards 14443 and 15693 - from physical layer up to session layer. We then continue to look at the typical architecture of RFID readers. The second part covers "librfid", the GPL licensed Free Software implemetation of an ISO 14443 and 15693 host-side stack. In Milosch's part we also give an insight into our current progress in home-brewn hardware and software defined radio (SDR) based passive sniffing of the RFID radio interface. After all, who wouldn't want to have "tcpdump" like functionality for RFID?

This device is deprecated - we instead provide the OpenPICC device for sniffing Reader-To-Tag data and for RFID tag emulation. For short range sniffing GNUradio and a simple passive loop antenna does a great job.
